Overall, they are in very well cared for condition. I dont know who made them or the exact age, but Im going to guess the 1920s.
They stand 2.25 tall with the cup in place, the saucer is 3.5 wide and the cup top is approx 2 diameter. Both the plate and holder are marked sterling and the makers mark.
